Answer:

3 electrons is contributed from each Nitrogen atom.

Total 6 electrons are shared in N₂.

Explanation:

Nitrogen is belong to group VA
it have 5 electron in its outer most Shell.
it need 3 electrons complete its octet to become stable.
Nitrogen have total 7 electrons.
its atomic number is 7

The electronic configuration of Nitrogen is as:

1s², 2s², 2p³

it exist in diatomic form standard temperature and pressure.

Nitrogen form covalent bond and share 3 electron from each side.

total 6 electron are shared between 2 nitrogen atom.

For Covalent bonding it can share its 3 electrons.

The diagrammatic representation is in attachment.

Which graph shows the relationship between the temperature and volume of agas according to Charles's law?Volume vs. Temperature

solmaris [256]

Graph D.

Charles's law states that at the same pressure, the Volumen of a gas is proportional to its temperature (absolute temperature).

This is

V = K T, where K is the constant of proportionallity.

You can also write it in the form

V1 / V2 = T1/ Ts

When Temperature rise Volumen rise in a proportional way. If Temperature doubles Volumen doubles, if Tempearature is decreases to on third, Volume will decrease to one third.

A gas originally at 27 °c and 1.00 atm pressure in a 2.6 l flask is cooled at constant pressure until the temperature is 11 °c.

elena55 [62]

Charles law gives the relationship between volume and temperature of gas at constant pressure
it states that at constant pressure, volume of gas is directly proportional to temperature
V/T = k
where V - volume T - temperature and k - constant
$\frac{V1}{T1} = \frac{V2}{T2}$
parameters for the first instance are on the left side of the equation and parameters for the second instance are on the right side of the equation
T1 - temperature in Kelvin - 27 °C + 273 = 300 K
T2 - 11 °C + 273 = 284 K
substituting the values in the equation
2.6 L / 300 K = V / 284 K
V = 2.46 L
New volume of the gas is 2.46 L

HNO₃ + H₂S → S + NO + H₂<span>O

Assign Oxidation Number:

L.H.S R.H.S
N in HNO</span>₃ = +5 +2 = N in NO
S in H₂S = -2 0 = S in S

Write Half cell Reactions:
Reduction Reaction:
3e⁻ + HNO₃ → NO -------(1)
Oxidation Reaction:
H₂S → S + 2e⁻ -------(2)

Multiply eq. 1 with 2 and eq. 2 with 3 to balance electrons.

6e⁻ + 2 HNO₃ → 2 NO

3 H₂S → 3 S +  6e⁻
Cancel e⁻s,
______________________________

2 HNO₃ + 3 H₂S → 2 NO + 3 S + H₂O

Balance Oxygen Atoms by multiplying H₂O with 4, Hydrogen atoms will automatically get balance.

2 HNO₃ + 3 H₂S → 2 NO + 3 S + 4H₂O
